CUBE Urban Concept Bike

The result of the coperation with the University Coburg/Germany (Productdesigner Gregor Dauth, Professor Gerhard Kampe) shows a 28″ wheel folding bike.

Here are the main features of the concept:

CUBE has a sportive bicycle portfolio. So the customers are focused on a sportive urban bicycl concept.

The lightweight urban bike can easily carried into the flat and the working place.

Two folding links to fold the bike and transport for long distance travel (Car, train, plane)

Interesting to see that also here a internally geared hub with 8 speed is used (See also Cannondale Sram Projekt ONE with a Sram i-MOTION 9 hub). The hole drivetrain is completely capsuled. This protects the chain from rain, dust,….. I cannot understand that there are so many urban bicycles on the market who disregard this fundamental necessity! The HEBIE Chainglider is a revolutionary invention and nearly no bicycle maufacturer uses this fantastic part. Also in this bike concept the essential urban fenders are missing. Who wants to ride with this bicycle to work on a rainiy day! Sorry!!!! Maybe most of todays urban bikes are looking better without fenders and capsuled a drivetrain but when you face real world the cool design will not protect the designer cloth from getting dirty.

The 28″ rear wheel can be released out of the frame. The rear pinion gear and the rear brake disc rests on the frame. This means the rear wheel looks more or less like a front wheel. There are no additional parts on any side of the hub. This has the advantage, that no oil or dirt from the rear pinion gear can touch your clothes and it´s much thiner part to store.

Also interesting to see that the rear brake disc is mounted on the derailer side. This is the opposite side compared to actual bicycles. Do YOU have any idea why?

This urban bike concept is another proof how bright the future of internal geared hubs is. Check also the Bicycle Design Blog for a deeper sight…
